Rashi on Exodus 8:22/רש"י על שמות ח׳:כ״ב

1תועבת מצרים THE ABOMINATION OF THE EGYPTIANS — This means: that which the Egyptians reverence (their idol), just as, (2 Kings 23:13) “and for Milcom the abomination (תועבת) of the children of Ammon”, but in relation to the Israelites it (Scripture) calls it תועבה. We may explain these words in another sense also: תועבת מצרים — The act of sacrifice which we practise is a hateful thing to the Egyptians seing that we sacrifice their god (sheep which were reverenced as gods in Egypt).

2ולא יסקלנו — This must be read in the intonation of a question (although there is no interrogative prefix הֲ) AND WILL THEY NOT STONE US?
